SPECIFICATION forming part of Letters Patent No. 643,462, dated February 13, 1900.

Application filed July 15,1899. Serial No. 723,938. (No model.)

To aZZ whom it may concern:

Be it known that I, DWIGHT .I. BLISS, a citizen of the United States, residing at Carthage, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Water-Filters; and Ido declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in water-filters and the object is to simplify and improve the construction and increase the efficiency of the device.

To this end the invention consists in the construction, combination, and arrangement of the several elements of the device, as will be hereinafter more fully described, and particularly pointed out in the claim.

In the accompanying drawings the same reference characters indicate the same parts of the invention.

Figure 1 is a perspective view of my improved water-filt-er. Fig. 2 is a vertical central section, and Fig. 3 is a horizontal section on the line 3 3 of Fig. 2. Fig. 4 is a detail perspective View, partly in section, of another form of the filtering-cylinder. Fig. 5 is a detail view of the cleaner-stone frame.

1 denotes the cylindrical casing, and 2 the removable bottom, provided with a step-bearing 3 and a threaded orifice 4 to receive the waste-cock 5.

6 denotes the cap or cover, provided with a threaded inlet-orifice 7 to receive the inletpipe 8 and with a central orifice through which the tubular shaft 9 passes and with which the joint is formed by the packing-gland 10. The tubular shaft is provided with radial orifices 11 11, and both ends are threaded, the lower one to receive the flanged cap 12, which has a bearing in the step 3, and the upper threaded end receives the fitting 13, which is provided with a lateral crank-handle 14, terminating in a knob 15, and this fitting is also provided with a threaded socket 16 to receive the outlet-cock 17.

18 represents a flanged collar encompassing the tubular shaft, and 19 designates the filtering medium, which consists of a sleeve, of tripoli or other suitable porous stone, encompassing the tubular shaft and clamped between the collars 12 and 18, so as to rotate with said shaft.

24 denotes a frame formed with parallel arms 24 24', which are provided with eyes and encompass the tubular shaft 9 above and below the filtering-cylinder, and said frame is kept from revolving with the cylinder by a bracket a, which is fixed to the inner wall of the casing, as shown in Figs. 2 and 3.

20 denotes a spring-wire'frame formed with an eye 21, which engages the tubular shaft 9, and to its outer endsare fixed the vertical V-shaped shoes which carry the cleaner-stones 26, the inner faces of which have a bearing on the filter-cylinder 19.

' 23 23 denote wire rods which extend from the arm 24 to the cleaner-shoes and assist the spring-wire frame 20 in holding said shoes and the cleaner-stones against the cylinder.

In operation the water from the servicepipe 8 passes into the cylinder 1 and thence through the filtering-cylinder 19 and orifices 19' into the tubular shaft 9, whence it is drawn for use through the cook 17. When a sufficient amount of foreign matter has accumulated on the outside of the filtering-cylinder to retard the passage of the water through it, the waste-cock 5 is opened and the cook 17 closed. The cylinder 19 is then rotated by means of the shaft 9 and crank 14, and the abrading action of the cleaner-stone 26 removes the accumulated matter from the perous-stone cylinder, and which is carried off by the current of water discharging through the waste-cock.

In the detail view of the tripoli cylinder shown in Fig. 4 the cylinder is formed with a concentrically-arranged series of longitudinal parallel pockets 19, the upper ends of which stop a short distance below the upper edge of the cylinder, while their lower ends communicate by means of the radiating grooves 19 with the axial orifice in the cylinder, and thence through the tubular shaft 9 and outletcock 17 The accompanying drawings show my invention in the best form now known to me; but many changes in the details might be made within the skill of a good mechanic without departing from the spirit of my invention as set forth in the claim at the end of this specification.

Having thus fully described my invention,

l the outer ends of said spring-wire frame, the what I claim, and desire to secure by Letters cleaner-stones 26 mounted in said shoes and the wire rods 23 23 connecting the said shoes and frame 2i, substantially as shown and described.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- Patent, is-

In a filter of the class described, the casing, a bracket a fixed therein, in combination with the tubular and radially-orificed shaft f), the porous filtering cylinder mounted 011 said shaft, the frame 24 engaging said bracket, nesses. and formed with the parallel arms 24 24 en- DWIGHT J. BLISS. compassing said shaft above and below said Vitnesses:

cylinder, the spring-wire frame 20 encompassing said shaft, the cleaner-shoes 25 fixed to T1108. HACKNEY, O. B. STICKNEY.
